(* ::Text:: *)
(*Amplitude is a database of Feynman amplitudes. Amplitude["name"] returns the amplitude corresponding to the string "name". A list of all defined names is obtained with Amplitude[]. New amplitudes can be added to the file "Amplitude.m". It is strongly recommended to use names that reflect the process. The option Gauge -> 1 means `t Hooft Feynman gauge; Polarization -> 0 gives unpolarized OPE-type amplitudes, Polarization -> 1 the polarized ones..*)
